Hello dear
Understand your concern.
Following are the cause of your problem:
1. VAGINAL WALL TRAUMA: bleeding cause pain in abdomen
It can be prevented by using lubrication during intercourse.
But may be due to urethral dysfunction.
2.
Precancerous condition in cervix: Atrophied cervix get easily damage due to trauma and produce pinkish blood due to mixed with cervical mucus
3. Endo metrial dysplasia
4. Cervical polyp
5. Fibroids
6. Ovarian cyst
7. Rough sex
So it might be a trauma to vaginal wall.
But if it will not respond you should consult with gynecologist/
sexologist to exclude precancerous condition and infection(STD:
bacterial vaginosis an chlymadia)
Do the following test:
1. Pelvic examination
2. Pelvic USG
3. Hysteroscopy
4. Endometrial biopsy
5. For
infertility do the sperm analysis of your partner at infertility centre.
Do
ovarian follicle study.
You should maintain hygiene before and after sex.
Use condoms and lubricants.
Take the advice of sexologist for better sex
wash vagina using warm water with added salt.
Wear loose cotton underwear.
Take healthy diet.
Hope this may help you
Wish you good health
